Long Ozon listings like “S07+D-120-320-1000-A10-X41” look cryptic — they’re the Sy Tools A10X41 combo sharpening system: an A10 clamp, an X41 module and multi-grit diamond combos bundled into one fixed-angle workstation. I’m Engineer Yanchi Li from Ruimo Tech; here’s an honest teardown.

A10 = the precision clamp that holds the blade and locks the angle; X41 = the companion module (support/rail) that also accepts the Sy Tools KD-A11 leather strop for finishing; the D-series diamond combo (e.g. D-120-320-1000) does the cutting. Verified Ozon SKUs: S07+A10+X41S09+A21+A10.

| Sy Tools kit | Diamond combo | Clamp/module | My take |
|---|---|---|---|
| S07+D-120-320-1000-A10-X41 | D-120-320-1000 (coarse→mid) | A10 + X41 | Best-value entry fixed-angle, 3 grits |
| S09+D-80-200-500-600-1000-A21-A10 | D-80-200-500-600-1000 (full) | A21 + A10 | Enthusiast full-range闭环 |
Both kits center on Sy Tools D-series electroplated diamond (160×22×8 mm, fits Ruixin/Tsprof/KME clamps). Difference is clamp model and grit coverage.
For a fixed-angle start: S07+D-120-320-1000-A10-X41. For full range: S09+D-80-200-500-600-1000-A21-A10. Finish with Sy Tools KD-A11; reference angle with Sy Tools T05-AMZ. Price/stock on Ozon live page (kits ~$14.99).
